at relatively slow speed so that the oscillations of the supporting sleeve 33 are comparatively slow, of the rate approximately of one oscillation per second. The amplitude of oscillation is in general the distance of 1.1/2 to 2 times the spacing between successive partitions. This means that the yarn carried between adjacent partitions is spread over the feed roll a distance equal to 11/2 to 2 times the width of the partition, thus providing an overlap of successive positioned yarns so that the whole feed roll is covered uniformly.

This is really the criterion as far as the amplitude of oscillation is concerned. It is desired to spread the wool fibers substantially uniformly over thc initial feed rolls so that when they reach the doffer roll 17 and the stripper roll 13 at the other end of the machine, the uniformity is very accurately established. Slight irregularities are eliminated through the transfer from roll to roll from the feed roll to the other end of the machine. At thc doler end of the machine, the fibers are stripped and from the right half they are carried off laterally or transversely to the right end of the machine and from the left half of the machine to the left end of the machine making two independent strands. The fibers nearest the midline of the machine on the stripper i3 form the inner section of the core of the filler while those fibers which are more towards the outer sides of the machine form the outer coatings for the core. That is to say, the bers in a position A (Figure l) will form the center of the core. Those in position B will come next to the center of the core, while those fibers in position D will form the outside cover of a core. The yarn 14, as it comes off the machine, will therefore have the filler fibers placed in a position around a center axis of the yarn or the core in accordance with the position in which the yarns will feed into the feeder rolls. The yarn originating from the strand 7 will be the center. Over this will be carried the coating originating from the yarn 6 and successive coatings from the yarns 5, 4, 3, and 2. The same situation exists with the yarns on the left hand side of the machine. There is of course some intermingling and overlapping and this is desirable, although by closely adjusting the amplitude of oscillation of the shaft 2S this can to a great extent be controlled.

The method and invention described is particularly useful when a particular color coating is desired for the yarn. Often times the yarn ller color will show. In this case, the desired outer coating is contributed by the yarns 2, 3 or perhaps 2, 3, 4 depending upon the thickness of the coating desired. For instance, if a white coating is desired, then a white yarn will be used for the yarns 2, 3, and 4. Similarly, if a particular kind of coating or a coating of long bers are desired, these will be used for the yarns 2, 3 or 2, 3, and 4. In this way, ordinary stock can be used for the inner yarns and special stock for the outer coatings. Combination of colors can also be obtained. For instance, it may be desired to have the core coated red and the outside coated white, or the inside may not bc dyed at all and the outside coated white.

A further advantage in the present system is that yarns can be given successive change of colors. All that is necessary in this case is to start the yarn 2 with a certain color and then change the ball substituting a yarn of another color. The method of operation is extremely flexible and almost any desired combination mayf readily and easily be produced.

Having now described my invention, I claim:

l. In combination with a carding machine having feed rolls for making yarn fillers, means for feeding separate yarns to said feed rolls at spaced intervals across the machine and means for continuously oscillating the yarn within given limits with respect to the feed rolls of the machine longitudinally thereof during the rotation of the feed rolls.

2. In combination with a carding machine having feed rolls for making yarn fillers, means for feeding separate yarns to said feed rolls at spaced intervals across the machine comprising a bar member having elements carrying spaced partitions, means positioning said partitions adjacent said feed rolls in desired spaced alignment, one with the other, and means for reciprocating said bar member longitudinally of itself comprising a level wind drive having a desired amplitude and means coupling said drive to said bar member.

3. In combination with a carding machine having feed rolls for making yarn fillers, means for feeding separate yarns to said feed rolls at spaced intervals across the machine, means for continuously oscillating the yarn during its feeding within given limits with respect to said spaced intervals, said limits comprising 11/2 to 2 times the spacing of said spaced intervals.

4. In combination with a carding machine having feed rolls for making yarn llers, means for feeding separate yarns to said feed rolls at spaced intervals across the machine, said means comprising a supporting bar means mounting said supporting bar parallel to the feed rolls and closely spaced therefrom, a plurality of partitioning elements spaced on said bar and means for oscillating said bar with said partitioning elements longitudinally of the bar itself.

5. In combination with a carding machine having feed rolls for making yarn fillers, a plurality of independent filler yarns, means containing said yarns positioned in front of the feeding end of said machine, means for feeding said separate filler yarns from said containers to the feed rolls of said machine at spaced intervals across the machine comprising a bar member, means forming spaced partitions on said bar member between which said separate filler yarns pass and means for reciprocating said bar member and said partitions for distributing said filler yarns over a definite sector of said feed rolls.

6. In combination with a carding machine having fecd rolls for making yarn fillers, a plurality of independent filler yarns, means containing said yarns positioned in front of the feeding end of said machine, means for feeding said separate filler yarns from said containers to the feed rolls of said machine at spaced intervals across the machine comprising a bar member, means forming spaced partitions on said bar member between which said separate ller yarns pass and means for reciprocating said bar member and said partitions for distributing said filler yarns over a definite sector of said feed rolls, said reciprocations having a limit of 11/2 to 2 times the spacing of said partitions whereby the distribution of one yarn on said feed rolls will at its edges overlap the adjacent yarns on said feed rolls.

7. In combination with a carding machine having feed rolls for making yarn fillers, means for feeding separate yarns to said feed rolls at spaced intervals across the ina-- chine, said means comprising a supporting bar, a plurality of partitioning elements spaced on said bar, means adjustably supporting said supporting bar including a plurality of connecting links for positioning said partitioning elements close to the feed rolls, a shaft supported on said machine for free movement in the longitudinal direction of said shaft, said links being supported on said shaft, and means for reciprocating said shaft, whereby said partitioning elements reciprocate longitudinally adjacent said feed rolls.
